About Dieffenbachia
Dieffenbachia fournieri, also known as Fournier's Dumb Cane, is a striking indoor plant valued for its lush foliage. It features large, oval-shaped, dark green leaves adorned with a prominent pattern of silvery or whitish veins running down the center and branching out, creating a distinct visual contrast. It is ideal for adding a tropical and sophisticated touch to living rooms, offices, or any well-lit indoor space.

Care tips
It prefers bright, indirect light; avoid direct sunlight which can scorch its leaves. Water when the top layer of the substrate feels dry to the touch, reducing frequency in winter to prevent waterlogging. Use a well-draining, organic-rich substrate, ideally an indoor plant potting mix. A common mistake is overwatering, which can lead to root rot and yellowing leaves; ensure the pot has good drainage.
